Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of an angle-adjustable elbow in which the angle can be adjusted freely.

[Prior Art] Conventionally, as an angle adjustable elbow, an upper pipe member is formed by an upper mouth pipe that is fitted and connected to a vertical gutter and an upper connecting pipe that is curved in an arc, and is fitted into a vertical gutter. A lower pipe member is formed by a lower mouth pipe to be connected and an arc-shaped lower connecting pipe, and an upper pipe member and a lower pipe member are slidably fitted and connected to each other to connect the upper pipe member and the lower pipe member. There is.

[Problems to be Solved by the Invention] In such a device, the angle between the upper pipe member and the lower pipe member can be freely changed by changing the insertion depth of the upper connecting pipe of the upper pipe member and the lower connecting pipe of the lower pipe member. Although it can be changed, when adjusting the angle, there is no reference for the angle,
There is a problem that the workability is poor because it takes time to adjust the angle.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an angle-adjustable elbow capable of adjusting an angle with a mark plate as a guide and improving workability. is there.

[Means for Solving the Problems] An angle-adjustable elbow according to the present invention for achieving the above object is composed of an upper pipe 1 which is fitted into a vertical gutter and is connected thereto, and an upper connecting pipe 2 which is curved in an arc shape. The lower pipe member 4 is formed by the lower pipe 4 which forms the member 3 and is connected to the vertical gutter and connected, and the lower connecting pipe 5 which is curved in an arc shape, and the upper pipe member 3 and the lower pipe member 6 are joined together. The connecting pipe 2 and the lower connecting pipe 5 are slidably fitted and connected to each other so that the angle can be freely adjusted depending on the fitting depth, and the upper connecting pipe 2 to the lower connecting pipe 5 are fitted to the outer surface of the fitted side. A plurality of mark plates 7 for displaying angles in directions are provided so as to be freely folded.

[Operation] When changing the fitting depth of the upper connecting pipe 2 and the lower connecting pipe 5 to adjust the angle, the unnecessary mark plate 7 is broken up to the fitting depth.
The angle can be easily adjusted by positioning with a predetermined mark plate 7.

[Embodiment] First, an embodiment of a gutter-shaped elbow will be described with reference to FIGS. 1 to 3. The elbow A is mainly composed of an upper pipe member 3 and a lower pipe member 6. As shown in FIG. 2, the upper pipe member 3 is formed by integrally providing a square tubular upper mouth pipe 1 and a square tubular upper connecting pipe 2, and the upper connecting pipe 2 is curved in an arc shape. In addition, concave strips 8 are provided on both sides of the upper mouth pipe 1 in conformity with the shape of the vertical gutter. As shown in FIG. 3, the lower pipe member 6 is formed by integrally providing a rectangular tubular lower opening pipe 4 and a rectangular tubular lower connecting pipe 5, and the lower connecting pipe 5 is curved in an arc shape. The lower mouth pipe 4 is also provided with a concave strip 8. On the outer surface of the upper connecting pipe 2 of the upper pipe member 3, a plurality of mark plates 7 are provided to project in the longitudinal direction,
This mark plate 7 is made foldable. This mark plate 7
Are sequentially numbered as 2,4,6,8,10. The elbow A is assembled by connecting the upper pipe member 3 and the lower pipe member 6 by fitting and inserting the upper connecting pipe 2 and the lower connecting pipe 5. By sliding the lower connecting pipe 5 with respect to the upper connecting pipe 2, the angle between the upper pipe member 3 and the lower pipe member 6 can be changed. The unnecessary marking plate 7 is broken off, and the end portion of the lower connecting pipe 5 is brought into contact with a predetermined marking plate 7 so that the end of the lower connecting pipe 5 can be positioned and adjusted to an appropriate angle. That is, as shown in FIG. 1, when the angle is adjusted so as to be positioned on the marking plate 7 having the number "8", "2""4"
The mark plate 7 with the number “6” is broken off, and the mark plate 7 with the number “8” is positioned so that the end portion of the lower connecting pipe 5 is brought into contact with the mark plate 7 and the angle is set. After adjusting the angle of the elbow A, the upper connecting pipe 2 and the lower connecting pipe 5 are bonded with an adhesive. At this time, the end portion of the lower connecting pipe 5 is positioned on a predetermined mark plate 7 so that the position does not shift. It can be temporarily held and adhered. As shown in FIG. 4, the elbow A constructed in this manner is mounted on the roof 11 of the first floor 10 of the building 9 at a corner between the first floor 10 and the second floor 12, and the upper mouth pipe 1 Is connected to the lower end of the downspout 13 of the second floor 12, and the lower gutter 5 is connected to the downspout 14 of the roof 11 of the first floor 10. At this time, even if the roof slope of the roof 11 of the first floor 10 changes, the angle of the elbow A can be easily adjusted and construction can be performed.

Further, FIG. 5 shows another embodiment, which is a case of a circular gutter. In this case, the upper mouth pipe 1, the upper connecting pipe 2, the lower connecting pipe 5 and the lower mouth pipe 4 of the upper pipe member 3 are cylindrical, and the upper connecting pipe 2 is provided with a positioning groove 15. At the same time, a positioning protrusion 16 is provided on the lower connecting pipe 5, and the positioning protrusion 16 is locked in the positioning groove 15 so that the positioning is prevented from rotating. Other configurations are the same as those in the above embodiment.

[Effects of the Invention] As described above, the present invention allows the upper pipe member and the lower pipe member to be slidably inserted into the upper connecting pipe and the lower connecting pipe to be connected to each other so that the angle can be freely adjusted by the insertion depth. Since a plurality of mark plates for indicating an angle in the longitudinal direction are foldably projectingly provided on the outer surface of the connecting pipe or the lower connecting pipe to be fitted, the upper connecting pipe and the lower connecting pipe are fitted and inserted. When adjusting the angle by adjusting the depth, it is possible to adjust the angle by breaking up the unnecessary mark plate up to the predetermined mark plate and positioning so that the end part abuts on the predetermined mark plate. The angle can be adjusted as a guide, the angle can be easily adjusted and the construction can be done easily, and the angle can be determined by positioning so that the end part contacts the mark plate, so it can be set accurately to the predetermined angle. When possible, adjust the angle between the upper and lower connecting pipes and then bond them with adhesive. It can be temporarily fixed and is easy to bond.
